[jaelgti]

Hello friends, I have read this ecu obd 25187592 DCM3.7AP CHEVROLET CAPTIVA 2.2
at the end of the reading it gives a checksum error
I modified to remove some dtc, I need to correct checksum.
and most importantly, is it safe to write?

KESS V2/5.017

I leave the two files, original and modified

Thank you very much for your time
